Match Supremacies
These can be fantastically volatile and the game can swing more wildly than a full length yorker!
For example, the twenty20 quarter final between Notts and Kent went from one extreme to the other -Notts went from 82 for 0, to 130 all out! When the score was 82 for 0, the match supremacy was 35-42 runs in favour of Notts, yet by the end of the game the supremacy was 90 Kent/Notts as Kent knocked off the 139 required for the loss of just one wicket.
That meant there was a turnaround of 130 runs in the supremacy stakes! The moral of this tale is to set a target for potential winnings -then close out as soon as you reach it because things can change so quickly in twenty20. A healthy profit can turn into an unhealthy loss in one quick over.
Close Finishes
If a team is chasing a total of say 150, and they are 145 for 2 with two balls left then the spread firms have a real dilemma -it is impossible to set a realistic spread that will cover both outcomes (a win or loss for the batting team). If the batting team gets the runs then their supremacy will be 80 (1 wicket = 10 runs) but if they fall short then the bowling team will have the supremacy by however many runs by which they win.
In this situation, the spread firms usually suspend the markets with about three balls to go so that there is no chance of getting stung by the punters. If you do want to get involved in a situation like this then you should know what you are going to do in advance because the market may be suspended before you have chance to get in or to close out.
In tight situations like this, the odds always favour the batting team due to the size of the boundary that the fielding team has to defend and the ability of tail enders to propel the ball to the unlikeliest of places!
One more piece of advice is to trade via telephone in a tight finish -this way you are certain to be able to trade and get prices that you may not get if you are trading online.
Sixes & Fours
If you are dealing in the sixes total index or multiple boundaries then do your homework by checking out the size of the ground, previous games there and the past performances of possible six-hitters. The Australian and South African batsmen had a field day playing at small grounds in the West Indies at the recent 50 over world cup.
 Wides
Umpires do tend to be stricter on wides -anything down the legside is likely to be called. With bowlers trying to tie batsmen down there should be at least five wides called in every innings. This would put the multi-wides index in the high thirties.
Run Outs
When the push for quick runs is on there will be many a risky single taken -and with some of the world's top fielders on show, there should be at least three per match.
Batsmen's Total Runs
The spreads on individual batsmen's totals will be set lower than in test matches and one- day games due to the pressure on the player to score quick runs and take chances. It is well worth checking out a player's twenty20 statistics on www.cricinfo.com But don't just look at their average, because with some of them having played very few matches in this format it can be misleading, instead take note of their total number of runs and boundaries. For example, England's best batsman, Kevin Pietersen, has scored only 97 runs (ave 16.16) in his six twenty20 internationals to date -not quite the standard you would expect from KP.
Team's Total Runs
Unless the bowling conditions are extremely favourable, teams should reach a minimum of 140 from their allotted 20 overs, although 150-160 is a more competitive total. If you think that the total will be higher than the market price and are looking to buy then be aware that it will only rise if the batting team score more than the normal run per ball in any given over. If a side loses a wicket then the market total will drop by a figure that is appropriate to the stature of the batsman that is out -usually between 15-25.
